Sum A1200

Internal USB Keyboard Interface for Amiga 1200

The Sum adapter, which is based upon a 16-bit Microchip microcontroller, enables
you to connect USB HID keyboards to your Amiga. It has been designed to be installed
inside the A1200's casing.

The Sum adaper provides a built-in USB stack which enables USB HID keyboard support
without the need to install additional software drivers. The device installation procedure
is a matter of simply seating it upon the U7 chip located on A1200's motherboard.

An additional feature of the adapter is its "Bootloader" function allowing
future firmware upgrades. The Sum adapter comes with a dedicated configuration mode,
which becomes available when R-Shift and Pause keys are pressed simultaneously.
User preferences are saved to the built-in EEPROM, thanks to which the device is
already configured the next time you reconnect it.
